All panicking about the escape a killer (6)
I believe the answer is:
lethal
'all panicking about the escape a killer' is the definition.
I can't judge whether this defines the answer.
'all panicking about the escape a killer' is the wordplay.
'panicking' indicates anagramming the letters.
'about' is an insertion indicator.
'the escape a killer' becomes 'eth' (I can't explain this - if you can you should believe this answer much more).
'all' with letters rearranged gives 'lal'.
'lal' enclosing 'eth' is 'LETHAL'.
Can you help me to learn more?
(Other definitions for lethal that I've seen before include "Enough to cause death" , "Death-dealing" , "All the change can be deadly." , "describing a killer?" , "Killing" .)
